When summer turns to autumn then winter, leaves are supposed to turn yellow, then fall off. Green grasses are supposed to become a thing of the past. You are supposed to be sick. Because, if winter never came around, you would not appreciate the beauty of spring. You would not witness the beginning of blooming flowers. You would not be amazed by the slow revival of colours in a grey day. Hence, when those grey days come around, do not despair. Indeed, with hardship, comes ease.
